cDNA cloning and expression analysis of a Poncirus trifoliata CBF gene

Biologia plantarum, 2009
The transcription factors CBF/DREB play an important role during low temperature, drought and high-salt stress in higher plants. A new CBF (CRT/DRE binding factor) gene was cloned from trifoliate orange [Poncirus trifoliata (L.) Raf.] by RT-PCR with degenerate primers and rapid amplification of cDNA ends (RACE) techniques.

Physiological quality of citrandarins, Poncirus trifoliata and Sunki mandarin seeds

Comunicata Scientiae, 2019
Rangpur lime is the rootstock most used in Brazil, mainly due to its resistance to drought; however, it is susceptible to several diseases, requiring the search for other rootstocks tolerant to factors limiting citrus cultivation. In addition, the Brazilian legislation stipulates that citrus seeds can only be commercialized with at least 50 ...
